Electronic apparatus with hidden antenna

Abstract

The invention discloses an electric device with a hidden antenna comprising a metal frame, a substrate, an upper casing and a lower casing, wherein the upper casing, the metal frame and the lower casing form a cavity to store the substrate. The lower surface of the metal frame has a groove, wherein the hemline of the groove has a feed-in end, and both sides of the groove form a first short circuit end and a second short circuit which electrically connects to a metal surface of the substrate. Thereby, the metal frame uses the first short circuit end and the second short circuit end and feed-inend to form a half wave cycle antenna. Thus the electric device can use the metal frame to receive and transmit an electromagnetism signal.

Description

technical field [0001] The present invention relates to an electronic device with a hidden antenna, and in particular to an electronic device that utilizes a metal frame constituting a part of the casing of the electronic device to send and receive electromagnetic signals. Background technique [0002] At present, the communication mode of the public has gradually changed to wireless communication, and the wireless communication devices are becoming more and more diversified, such as smart phones, multimedia players, personal digital assistants and satellite navigators. Various electronic devices with wireless transmission function are also improved toward the design concept of light, thin and short, so as to achieve electronic products more suitable for daily use. [0003] Generally speaking, electronic devices operate through antennas to receive and transmit signals. In order to achieve miniaturization and design of a hidden antenna, most electronic devices use a monopole...

Problems solved by technology

However, since the loop antenna operates at all wavelengths, the electronic device must spend a huge amount of hardware space to configure the antenna

In other words, electronic devices that use loop antennas to send and receive electromagnetic signals often need to consume more hardware space, which limits the miniaturization design of electronic devices.
